Abstract: A piezoelectric transducer is described for generating focused ultrasound shockwaves for application in lithotripsy, whose ultrasound shockwaves, emitted in a pulsed manner, can be transmitted via a coupling medium (20) to the body of a patient. It consists of a multiplicity of individual piezoelectric transducer elements (2), of ceramic, which are connected to the terminals of a pulse generator (7) and are fixed in the form of a mosaic on a carrier (8) and are laterally insulated electrically from one another, the acoustic termination of the transducer elements (2) being essentially reflection-free. It is proposed that there be provided between the transducer elements (2) and the coupling medium (20) an intermediate medium consisting of at least one layer (3, 4, 5) whose acoustic impedance is between that of the ceramic of the transducer elements (2) and that of the coupling medium (20) and that the thickness d of the layer (3, 4, 5) be dimensioned such that the relationship d> tau k x cLA is true,  tau k being the propagation time of the sound in the piezoceramic material of the transducer elements (2) and CLA being the speed of sound in the respective intermediate medium.

Abstract: The apparatus for determining volatile gases and/or vapor components in a flowing liquid consists basically of a gas analysis instrument (8) which is charged via a sampling tube (9) with the components to be measured which have been freed from the liquid. A carrier gas (17) is passed through a gas inlet tube (11) into the flowing liquid and liberates the gas components to be measured, which are then passed together with the carrier gas (13) through the sampling tube (9) to the gas analysis instrument (8). For this purpose the sampling tube (9) is connected to a dip tube (3) which projects into the liquid and surrounds a porous distributor body (12) for introducing the carrier gas (13) in the form of finely disperse gas bubbles, which distributor body is connected to the gas inlet tube (11) and is subjected to the flow of liquid from the side.

Abstract: Spread spectrum chirps (i.e., wideband frequency packets) are propagated on a local area network in a hostile communications environment, such as a powerline or a crowded radio frequency band. Chirps are self-synchronizing, data bit (or subdata bit) in length and detectable by all network nodes, to allow the contention resolution and collision detection needed to support carrier-sense based network protocols. A matched filter of the same time length and encoding sequence as the transmitted chirp provides the self-synchronized chirp reception at each receiver.

Abstract: An optical switch employs a modified sagnac arrangement that includes a sagnac loop (10,11) and a coupler (20) for injecting a signal into the loop and developing thereby two signals (MARK,REF) that travel along the loop in opposite directions. The coupler has at least one signal port that is accessible from outside the switch. In addition, a coupler (30) is included to inject a pump signal into the loop to travel through the loop only in one direction. The loop is made of, or comprises, a material (11) that has a controllable propagation speed. More particularly, the propagation speed in the material is a function of, for example, the intensity of the pump signal. The switch action is attained when the applied signals are in the form of pulses with pulse widths and relative positions controlled to achieve a particular interaction. The switch action is observed by sending a pulse down a sagnac loop and observing its return. Switching is activated by either sending or not sending a pump pulse concurrently with the signal pulse that is sent down the sagnac loop. When a pump pulse is sent, it is timed to orient itself so that the pulse that propagates faster through the loop precedes the pulse that propagates slower. While propagating through the loop, the faster pulse overtakes and surpasses the slower pulse, causing the two pulses to traverse each other. In this manner the pump pulse affects the propagation speed of the pulse sent through the sagnac loop and modifies the phase of the affected pulse as it re-enters the sagnac coupler. When the intensity of the pump pulse is properly controlled, the phase shift caused by the pump pulse is such that no output appears at the port of the sagnac arrangement.
